Features
The construction of these units is based largely on that of the Nuove Unità Minori Combattenti (NUMC); the hull and superstructure incorporate stealth features. The NUMC and Nuove Unità di Pattugliamento d'Altura (NUPA) share logistics, interoperability, features of the combat system and integrated telecommunications systems.
Each unit has two Wärtsilä NSD- W12-26 V-XN diesel engines providing 8,640 kW (11,590 hp) to two variable-pitch propellers. The ships have a top speed of 22 knots (41 km/h; 25 mph) and a range of 3,300 nautical miles (6,100 km; 3,800 mi) at 14 knots (26 km/h; 16 mph). Three Isotta Fraschini 1708 T2 M2 600 kW (800 hp) diesel generators each power the on-board electronics. The armament consists of two Oerlikon KBA-Alenia Oto Melara 25/80 mm machine guns with the provision to bow mount an OTO Melara 76/62 mm Super Rapid. Each unit can embark a single helicopter, either an AB-212 ASW or SH-90A NFH, but the ships lack hangars. For antipollution roles, vessels are fitted with:
